Als Werkstoff für die Draht-Armierung 20 kommt bevorzugt ein Draht aus einer Legierung in Frage, welche Legierungsbestandteile aus Chrom, Aluminium und/oder Kobalt enthält. Die Hülle selbst kann aus einem hitsebeständigen Zement oder auch aus einer Kittmass« auf der Basis von Mineralfasern bestehen. A wire made of an alloy is preferably used as the material for the wire reinforcement 20, which alloy components made of chrome, aluminum and / or cobalt contains. The shell itself can from a hit-resistant cement or from a putty «based on mineral fibers.
Als Werkstoff für das Gehäuse kommt für alle Ausführungsformen bevorzugt ein Nickel-Chrom-legierter Stahl mit austenitischem Gefüge, der bis zu 1150° C hitze- und zunderbeständig ist, in Frage.A nickel-chromium alloy is preferably used as the material for the housing for all embodiments Steel with an austenitic structure that is heat and scaling resistant up to 1150 ° C is in question.
Die Dichtuügs- und Stützbänder bestehen vorteilhaft aus chemisch stabüen, unbrennbaren Mineralfasern, im wesentlichen aus Aluminiumoxyd und Siliziumoxyd. Die Bänder können gepreßt und/oder geflochten sein; sie können von einem Drahtnetz umge-The sealing and support bands are advantageous made of chemically stable, non-flammable mineral fibers, essentially made of aluminum oxide and silicon oxide.

6AIs Bindemittel ist ein an der Luft härtender oder unter Temperatureinwirkung aushärtbarer hitzebeständiger Werkstoff geeignet. Der Werkstoff muß beim Aufbringen der Hülle plastisch verformbar sein, damit er sich dem Raum zwischen Katalysatorkörper und Hülle anpassen kann. 6 A heat-resistant material that cures in air or cures under the action of temperature is suitable as a binder. The material must be plastically deformable when the shell is applied so that it can adapt to the space between the catalyst body and the shell.
Für den Katalysatorkörper selbst kommen unterschiedliche Werkstoffe in Frage, je nachdem, ob es sich um einen Oxydations- oder einen Reduktionskatalysator handelt.For the catalyst body itself, different materials come into question, depending on whether there is is an oxidation or a reduction catalyst.
Sein die feinen Durchströmungskanale enthaltendes Skelett besteht aus einem feuerfesten keramischen Werkstoff, beispielsweise aus Magnesium-S-likat Aluminiumoxyd, Zirkon od. dgl. Dieses Skelett diont als Träger für eine dünne Auflage aus dem Material mit der katalytischer Wirkung.Its skeleton containing the fine flow channels consists of a refractory ceramic Material, for example made of magnesium silicate Aluminum oxide, zirconium or the like. This skeleton diont as a carrier for a thin layer of the material with the catalytic effect.
